ROCK-DRI LL.

SPECIFICATION forming part of Letters Patent No. 232,609, dated September 28, 1880.

Application filed January 2l, 1880.

To all 'whom 'it 'may concern:

Be it known that I, SYLvANUs HUssEY, of Gowanda, in the county of' Cattaraugns and State of New York, have made certain lmprovements in Rock-Drills, ot' which the following is a specification.

This invention relates more particularly to drills operated by hand for mining purposes, although power may be applied, if desired; and the object of this invention is to get a more rapid stroke or blow on the rock than is now had by hand-drills, and obtained, also, with greatly less power, also,combining in one machine drilling` and tunneling by the movement of the operating parts in any direction desired; and the invention consists in the use and .application of two or more peculiar double combination gripes for operatingr the drill-bar; also, in a circular frame, which carries a series of friction-rollers and frictionwheels which operate the levers, they operating the gripes, 85e.; also, in the construction of the frame by which the operating parts are turned in any desired direction; also, in ad- 2 5 justable jaws for adjusting the down-feed of the drill-bar on the rock; also, in the construction of the parts containing the gripes and the devices for operating them, and theratchet device on the lower part for turning the drillbar and drill; and, iinally, in the arrangement of the crankgears and fly-wheels -by which the whole machine is operated and the motion facilitated andmade regular and even, all as fully hereinafter explained;

In the drawings, Figure 1 is a front elevation. Fig. 2 is a side elevation. Fig. 3 is a vertical cross-section through the parts that inclose and operate the drill-bar; Fig. 4, a plan of the cat-head and operating-levers; Figs. 5 and 6, details of ratchet-rings.

c a a are the legs or tripod, each foot being hollow to receive the extension-legs a! a a', as usual.

The top of the tripod is a disk, 11, on which rests another disk, Z1', with side projections, to which the side` pieces, A A, are bolted or otherwise fastened. These frames consist of two pieces of casting with segmental ways c c, which form guides for the turning of the drilling parts. In the upper part of this frame sets a loose shaft, d, on the outside ends of which, and outside the frame, are tly or balance wheels B B, with cog-wheelse @attached thereto. Meshing into these are large gearwheels O C,with cranks D for operating them. They are on the ends of a shaft, j', with bearings in arms g g, that project back froinattle .drill-frame E. The outer ends of these arms are connecte-d by a rod, h, the ends of which run in the segmental guides o, and which, by nuts on the ends, hold the drill-frame when tilted in any desired rotary position. disks b b', at the bottom, permit the turning of the frame and drilling parts longitudinally,

so by these devices any angle orV position desired indrilling or tunneling can be had.

On the operating-shaft 7" is a cat-head, consisting of two circular frames, t' t', and in them, on the connecting-rods ot' the frames, are set loose friction-rollers lo k k', (three or more.) Running loose on these rollers, and next the framesz i, are friction-wheels ZZ, of greater circumference than the rollers, the latter having shoulders to prevent a side movement of the wheels.

Setting loosely-on the shaft d are three operating-levers, as follows: In the center is the wide lever m, which is bent, and its center inclosing the shaft d. Its inner end is just wide enough to work between the two side frictionwheels, l L, and strike on all the friction-rollers 7o k at. every revolution of the cat-head. The front end of this lever is bifurcated, so as to inclose the drill-rod F, and has a supplementary slantin g piece, u, set on each, thereby forming adjustable jaws G. These pieces are slotted on the outside, and have a set-screw, o, in each to adjust them, so as to gage correctly the down-feed of the drill-bar on the rock. (See Figs. 4 and l.) Each side of this center lever, m, (on the same shaft -d,) are two other bent levers, p p, (see Fig. 1,) working loosely on the shaft, the inner ends being shorter than the end of lever m, and are operated by the friction-wheels l Z of the cat-head. To the front en ds of these levers are connected, by wrist-pins q q, pitmen r r, which are slotted at their upper ends and connected to the studs s s, which raise an inverted cone-shaped or inwardly-rounded piece, t, surrounding the drill-bar, and which is loose in an outside frame, w, screwed onto a central frame, u.

The devices to raise and hold the drill-bar are as follows: In the central hollow frame, u,

The i 'which is screw-threaded on the outside, are

arranged vertically two or more griping devices, c t, pivoted below their centers to the case u. These gripes are of peculiar construction. (See Fig. 3.) The lower ends are beveled oli and slide over a cone-shaped or rounded lifting-piece, w, loose on the drill-rod F, which, by the working of the lever m and jaws Cr, gripes the rod land raises it' up at the same time. Previous to this, however, the upper part of the gripes fr t, which were held by the inverted cone-piece t, have been released by the action ot' the levers p p and pitmen r r. When the parts reach their highest point the release of the levers from the friction-rollers Zand 7c drops the parts down. The inverted cone part t, just previous to this, catches the tops ofthe gripes u c, and holding them tightly, and also holding the drill on the rock, so that there is no rebound. This movable part H' falls only so far every time, being regulated by the feed; but it' it slips it strikes on an india-rubber bed in base I, attached to the drill-frame, to take off the shock and prevent noise. (See Fig. 2.)

In order to get the rotary movement ot" the bar, a circular' section, J, is screwed onto the the lower part of the frame u., with ratchetteeth around it.. Another circular frame, It, surrounds this, with a ratchet to engage with the teeth. is a pin, 'z which sets in a slotted sian ting guide, z, and as the drill-bar is raised the slanting slot turns the whole bar and gripe-frame every time just as much as required, the turning regulated by setting` the slotted guide z at a greater or less angle.

A circular ring, l, acting as a jam-nut, keeps the ratchet-frame It in place. Circular rings 2 3 are secured on the framevu, also act as jam-nuts, and regulate the exact positionot'the upper and lower parts.

The operation ot the machine is as follows: When set in proper position to drill, one or two persons will turn the crank-wheels revolving the cat-head frame with its friction rollers and wheels, which act on the levers m and p p. The lever m, raising the lifting-piece zr, its cone top pushes the lower ends of the gripes /slightly apart, and by theireccentric shape they at once seize the drill-bar and raise it and the entire surrounding frame. The jaws ot' the lever m., by the supplementary pieces n n, give greater or less feed to the bar, according to whether they are set out or in-thatis,they raise the bar and frame more or less, as desired. At every up movement of the bar it is seized a little higher up` by the top of the gripes being acted on by the up-and-down movement of the inverted cone-shaped part t, independently operated by the levers p p and pitmen r r.

()n the periphery ot' the frame R This gives the down-feed to the drill. At a certain point in the movement of the drill-bar holding the parts H the gripes are not on the bar, so that if the stone should be soft or a hole struck the bar would drop itself. This is an important point :in its construction. This up-feed ofthe drilling parts bythe eccentric supplementary jaws n n, also preventing the striking or pounding ofthe parts at every down movement of the drill-case H, is alsoimportant.

I claim- I. The frame for the working parts, consisting ot the side frames, A A, having the segmental ways or guides c c formed therein, the side arms, g g, and drill-frame E, and rod h, the latter swinging in the ways c c, all constructed and arranged substantially as hereininbefore specified.

2. In connection with the operating-shaft f and devices for turning it, the cat-head, consisting of the two disks i t', with the three or more loose friction-rollers lc k and wheels Z l, working therein, in combination with the levers m p p and shaft d, all substai'itially as and for the purpose specified.

3. In combination wit-h the hollow lift-ingpiece fr, having the cone shaped top and lian ged base, the lever m, with bifurcated ends forming the jaws Gr, either square or rounded, the supplementary slotted slanting pieces n n, and set-screw o, for adjusting the feed of the drill-bar, all substantially as specitied.

4.. The side levers, p p, on shaft d, the slotted pitmen q q, connected thereto and to studs s s, for raising the inverted cone t, all substantially as speciiied.

5. The combination of the two or more peculiar-shaped pivoted gripes, c c, the central frame, u, case fw, the loose lifting-piece t, and lifting-piece m, all arranged and operatin g substa-ntially as and for the purpose specified.
